SHARE PRICE ANALYZING DEVICE AND METHOD FOR GENERATING DATABASE FOR STORING ANALYTIC RESULT OF SHARE PRICE

PROBLEM TO BE SOLVED: To analyze relations between a document written about an enterprise and the share price change of the enterprise generated in a period when the document is issued. SOLUTION: An article data analyzing device 7 is provided with an article DB31 in which article data are stored, a vector generating part 72 which extracts a plurality of article data related to a certain enterprise from the article DB31 within a certain period, and extracts words included in the extracted article data, and generates a plurality of multi-dimensional vectors showing the article data based on the extracted words, a clustering part 73 which clusters the plurality of generated multi-dimensional vectors, a representative vector calculating part 74 which decides the representative vector of the cluster obtained by clustering, a sensitivity calculating part 75 which calculates the sensitivity of share price change in the period based on share prices at the beginning and end of the term and a vector DB21 in which the representative vector and the sensitivity of the share price change are stored so as to be associated with each other.
